COMBINED LETTER-SHEET AND ENVELOP.

Application led February 25, 1918. Serial No. 218,922.

To all whom t may concern:

Be it known that I, SAMUEL BRoD, a citizen of the United States, andresident of the city of New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements in CombinedLetter-Sheets and Envelops, of which the following is a specification.

This invention relates to combined envelops and letter sheets andespecially to that type which may be opened by the addressee in the samemanner as ordinary envelops.

The object of this invention is the provision of a letter sheet whichmay readily be folded and sealed into an envelop without the expenditureof labor greater than that required to fold and insert an ordinaryletter sheet into an envelop and to seal the envelop.

A further object of this invention is the provision of al combinedletter sheet and envelop which saves paper over the separate sheet andenvelop and which is inexpensive to manufacture.

A further object of this invention is the provision of a combined lettersheet and envelop in which the contents or writing cannot be tamperedwith without destroying the envelop or mutilating the sheet.

A still further object of this invention is the provision of a combinedletter sheet and envelop which can be inserted into the typefwriter asreadily as an ordinary sheet, and on which the address need be ywrittenonly once. Y

For the accomplishment of the aforesaid objects, I employ theconstruction shown in the accompanying drawings, in which- Figure 1 isa. view of that surface of the letter sheet upon which the writing is tobe done, as it appears when ready to be folded into an envelop.

Fig. 2 is a rear view of the folded and sealed envelop and Fig. 3 is afront view of the same inverted.

Figs. i and 5 show two of the steps neces i sary to fold the sheet intoan envelop.

In the practical embodiment of my invention, I employ the letter sheet1, which may be of any of the sizes `in ordinary use for commercial orsocial correspondence, and which is included between lines 16, 18 and17. Said sheet 1 is provided with a seal flap 3 and side liaps 2integral therewith. While Y Specication of Letters Patent.

the shape of seal flap 3 shown is that. used in ordinary commercialcorrespondence, it will be seen from what follows that said flap may beof any of the shapes used in correspondence of any nature withoutdeparting from the spirit of my invention. v f

Seal flap 3 is large enough so that the adv i ister with and showthrough .window 4C which is cut in the upper part of sheet 1 andwhich iscovered by transparent patch 5.

It is obvious that the window and patch in sheet 1 may be omitted andthe address written on the face of the envelop, if desired, instead ofon the seal flap.

Side flaps 2 are designed to fold about scores 13 continuous with thelongitudinal edges of sheet 1, into the position shown by the dottedlines in Fig. 1 to the rear of the sheet, so that said sheet 1 may beinserted into the typewriter and treated as is the letter sheet now ingeneral use. Said flaps 2 are cut away at S to allow the gummed portionof seal flap 3 at its center 7 to be pasted on to the body of the foldedsheet 1 asis shown in Fig. 2. |Ihe shape of said flaps f2, in general,is such that when folded into their final position in the envelop, theywill clear the window 4L (Fig. 2). When no window is used, flaps 2 maybe made substantially outline. quadrants of circles.

Transverse score 10is impressed on sheet 1 between the bottom corners offlaps 2 and defines the bottom edge of folded envelop 14. Additionaltransverse scores 9 and 11 are made in sheet 1 and serve to indicate theplace where said sheet is to be folded and to make easier-,the foldingthereof to the positions shown in Figs. 4i and 5. Thev distances betweenscores 10 and 9, 9 and 11, and 11 and edge 17 are all thesame and areequal preferably tov thedistance from score 10 up to the bottom edge ofpatch 5, when the window is used.

If no window is used, edge 17 of sheet 1 may be brought as close toscore 16 as may be desired, theplace where the fold occurs being scoredas at 9, the additional' scores 11 thereon, the upper part of said sealflap beand 10 being positioned suitably for making easy a second fold inthe sheet. 1t can readily be seen that for a bill or a. short lettersheet, that portion of the sheet 1 below score 9 may be omitted entirelywithout affecting the final folded envelop.

Longitudinal scores 12 in sheet 1 define the lateral edges of foldedenvelop 14', and on their distance from the longitudinal edges of sheet1 depends the size of the portion of flap 2 which projects beyond thesheet proper. lVhen it is desired that the flaps 2 be small, scores 12are placed close together, but where a large envelop is wanted, thedistance between scores 12 must be increased.

My new product is used as follows:

The sheet arriving at the consuine-rs with flaps 2 folded back out ofthe way, looks like the ordinary letter sheet excepting for the sealflap, scores and window. The sheet is written on in the typewriter or byhand, addressed on the seal flap as shown in Fig. 1, and is ready forfolding into an envelop. Edge 17 is brought up to the bottoni edge ofpatch 5, a fold being made on score 9 (Fig. 4). Score 11 is nowregistered direetly above score 10 and the second fold may then be made,thereby forming one edge of the envelop along score 10. Portions 15between scores 12 and the edges of sheet 1 are, by this means, foldedtogether with the remainder of the sheet and are now ready to be foldedtogether with flap 2. Said flaps and portions 15 are folded on scores l2(Fig. and the seal iap 3 then pasted on to the said side flaps and thatpart of the sheet exposed by the eut-away parts S of the side flaps,thereby completing the envelop.

It will be seen that the labor of folding the sheet is little, if any,more than that involved in folding the .ordinary letter sheet. insertingit into the ordinary envelop and sealing the envelop. A large party ofthe paper required for making an envelop is dispensed with, printinglabor is saved in view of the ease in printing both sides of myiniproved product, and it will be seen that the postmark appears on theback of the sheet after mailing.

Two or more thicknesses of material are presented everywhere except onthe curved parts of the side flaps, which are not greatly exposed toinjury, whereby a strong envelop is produced. The letter can not betampered with without destroying the envelop and sheet, sincethe foldedportions 15 prevent the sheet proper from being drawn out from under theside flaps 2 after folding thereof.

To open the folded envelop, the seal flap is eut along score 16 andremoved, or opened or destroyed in the saine manner as is that of theordinary envelop, without any injury being caused to the contents of theletter. While the central portion 7 of gum strip 6 .is attached to thesheet 1, it is easily removed after the envelop is eut at score 16,allowing the sheet to open without difficulty.

Vhat l claim is:

1. A letter sheet having a window in the upper part thereof, a seal flapintegral with said sheet and adapted to have an address written thereon,and side flaps shaped to clear said window when folded, said seal flapwhen folded being arranged to lie on the folded side flaps, said windowbeing arranged so that the address on the folded seal. i'iap is visibletherethrough when said sheet is folded into an envelop.

2. ln a combined letter sheet and envelop, a seal flap adapted to havean address written thereon. side flaps and an extended bottom flaphaving window in the upper end thereof, said window being arranged sothat the address on the seal flap is visible therethrough when saidsheet is folded into an envelop, said bottom flap being arranged to befolded to a line below said window and adapted to be held under saidside and seal flaps, said seal flap being` arranged when folded to lieon said side flaps.

3. A letter sheet having a window in the npper end thereof, a seal flapintegral with said sheet, side iiaps shaped to clear said window whenfolded, scores on which said sheet may be folded lon gitndinally intonarrow strips of uniform width and trans versely up under said sideflaps to a line below said window to be held by said side flaps and sealflap to form an envelop, and a transparent patch guinmed to said sheetover said window.
